DropGuard

DropGuard 2.9.4

• New exact-variant rules serialize actual item components, including nested shulker contents. Different contents no longer share protection merely because their debug strings match.
• Component identity is independent of object-key order. Durability and stack count remain excluded from exact-variant matching.
• Added protection for Creative hotbar throws and outside cursor drops.
• User-initiated inventory closing is blocked when a protected cursor item cannot fit back into the inventory. Both screen closing and the player close-container path are checked. The existing bypass chord still applies.
• Fixed duplicate drops when the bypass chord includes the normal drop key, and prevented repeated queued menu events from opening nested menus.
• Preserved corrupt configuration files before recovery, retained existing protections and migration behavior, and avoided redundant settings writes.
• Invalid key bindings now display as Unbound. Missing modded items retain their saved name or registry ID instead of appearing as Air.
• Added a bounded component-identity cache that clears on disconnect or registry changes.

Compatibility notes

Existing v2 and older rules remain supported. Ambiguous old v2 shulker rules cannot be reconstructed from data that was never stored; remove and reselect an affected exact-variant rule to create a precise v3 rule. Existing rules are not silently discarded.

The new close check covers the cursor item. Overflow from automatically returned crafting or anvil input items is not covered. Server-forced closure and server-driven item removal are not guaranteed to be prevented. Third-party components whose codecs fail retain legacy identity behavior.

Requires Fabric Loader and Fabric API. Client-side mod; use the file matching your Minecraft version.
